Is your feature request related to a problem?

Currently, we use the @Constant annotation to mark parameters as constant (i.e. a literal must be passed). This is an important concept, however, e.g. for partial evaluation or refined types, so a modifier might be better suited.

Desired solution

  • Add a const modifier for this purpose.
  • For annotations, show an info if the modifier is used, since it is implied. Or should we show an error if it's not used?
  • Error if lambda parameters have this modifier
  • Error if parameters of callable type have this modifier

feat: const modifier to replace @Constant annotation (#618)
ea4a9ba 
Closes #558

### Summary of Changes

Add a `const` modifier for parameters to indicate that they only accept
values that can be evaluated to a constant expression at compile-time.
This replaces the original `@Constant` annotation.
